Ingalungiswa ku-switch cabinet noma ifakwe enqoleni yesandla.
Ukusebenza okuzinzile nokufakwa kalula.
Vacuum Indoor Circuit Breaker Product Scope
Izinqamuli zesekethe zamandla kagesi amaphakathi zokusabalalisa okuyisisekelo kufika ku-24 kV, 3150 A (4000*), 50 kA.
Izinzuzo ezibalulekile ze-Circuit Breaker
1.Isakhiwo esilula.
2.I-Adaptha isiphazamisi se-vacuum esiphansi kakhulu sokumelana nohlobo.
3.I-Adapta optimization kanye ne-modular spring operating mechanism.
4.Ifanele izikhathi ezisebenza njalo.
5.Ukugcinwa kwamahhala kanye nempilo ende yesevisi.
6.Ukusebenza okuphezulu okuthembekile.
Iphaneli ye-vcb yasendlini ye-vacuum breaker panel 11kV vcb panel
Izimo Zemvelo
Izinga lokushisa le-ambient: - 40°C~+40°C (ngaphansi kuka-35°C phakathi namahora angu-24)
Umswakamo ohlobene: ≤95% (isilinganiso sansuku zonke) noma ≤90% (isilinganiso sanyanga zonke)
Ukuphakama: ≤ 1000m
Indlela yokusebenza iwuhlobo lwamandla agciniwe angenawo uhambo olunokuvulwa nokuvala okuzimele ngaphandle kokunaka isenzo somqhubi.Indlela yokusebenza isetshenziswa kabanzi kuwo wonke ama-circuit breaker we-VD4-R anokulawula okungaphambili.
I-circuit breaker ingalawulwa ukude uma ifakelwe izesekeli zikagesi ezizinikele (i-gearmotor, ukukhululwa kokuvula nokuvala).
Indlela yokusebenza, izigxobo ezintathu kanye nezinzwa zamanje (uma zihlinzekiwe) zifakwe ohlakeni lwensimbi olungenamasondo.Ukwakhiwa kuhlangene ikakhulukazi, kuqinile futhi kunesisindo esilinganiselwe.
I-VD4-R yochungechunge lwama-circuit breaker anendlela yokusebenza yangemuva ingamadivayisi engcindezi avalwe impilo yonke.(Izimiso IEC 62271-100)
